mosser (addictive puzzle game) on Lua

This is a simple lua port of "mosser" made by kuni (http://www.din.or.jp/~ku_/ ).
"mosser" is a award winning puzzle game in "HSP contest 2004".
This game is very addictive, so you should be careful!?

#HOW TO INSTALL
First get luaplayer at http://www.luaplayer.org/ .
put "luamosser" folder to
\PSP\GAME\luaplayer\Applications
Launch LuaPlayer and select "luamosser" on Lua Lowser.

I myself played and tested on FW1.5 PSP with luaplayer v0.18. 0.19
(the newest 0.20 causes errors.)

#HOW TO PLAY
Put moxa to lead fire and burn'em all.
It comes to a gameover under these conditions.
1) the remaining moxa reaches to the bottom.
2) you are packed in by moxa in 4 direction, so you cannot move.

#CONTROL
Move to up,down,left,right by the digital pad.
start = quit game to Lua Lowser

#HINT
The moxa ignites slowly, so if you put moxa linearly,
a lot of residual moxa reaches to the bottom.
Pass by firing point periodically to make a shotcut.

#MISC
Erase "hiscore" file to initialize highest score.
This program records replay data.
Before playing it runs playback data of "hiscore".
After playing, it runs playback of the last play.
